Museum of Riverside

Renovation & Expansion

Riverside, California

The rehabilitation of the historic 1912 Federal Post
Office includes the removal and replacement of the existing rear addition to the south side of the building with a new dynamic two-story structure with a roof terrace that is modern in appearance yet complimentary to the historic structure. Nestled between the new addition and the historic building is a new universal access entry opening into a grand lobby space connecting new and old. The exhibit box addition is designed to be compatible with the historic Mission Revival style of the post office and surrounding structures by using
a similar materials palette and articulation of fenestration while providing the museum with a temperature and humidity controlled environment for exhibits. New hardscape and exterior learning areas supplement the interior exhibits to celebrate the museum’s mission of sustainability and regional education.A recent addition to the program included a sustainability component to go for LEED Gold.
